I don’t know where you are from but seeing sauna gain popularity outside Finland and Estonia lately has been refreshing. It is commonplace thing here and I don’t think we attach so much theory or consider ”using” it for any particular reason because it is so mundane. Maybe if you intentionally have to go to lengths to do it then you also think about the meaning of doing it more deeply.
Not to be rude, but to expand how this sounds to me - It’s like going to shower to incorporate shower thoughts to be part of your daily routine. Which is profound but at the same time
somehow narrow view of the whole routine and tradition of having showers.
